چکیده مقاله :
برای ارتباط سنجی بین کانی زایی مس پورفیری و سیستم های گسلی، کانسارهای پورفیری علی آباد و پورفیری– اسکارن دره زرشک در كمربند ماگمایی اروميه– دختر انتخاب شدند. در این پژوهش سعی شد این ارتباط با استفاده از داده های سطحی و زیرسطحی (اطلاعات حاصل از حفاری های صورت گرفته در قالب اطلاعات ژئوتکنیکی و میزان عیار مس) در محل کانسارهای علی آباد و دره زرشک، روشن شود. نتایج این مطالعات نشان داد که کمربند های گسلشی که از طریق بررسی معیار میزان کیفیت سنگ (RQD) به‌دست‌آمده انطباق به نسبت خوبی با گسل-هایی که از طریق مطالعات سطحی و روش های سنجش از دور به‌دست آمده اند، دارند. همچنین در طول این پهنه های گسلیده عیار کانه زایی مس بالاتر می باشد، به این ترتیب، ارتباط کانه زایی و گسلش در منطقه اثبات می شود.
In order to find the relationship between porphyry copper depositions with faulting systems, the Aliabad porphyry and Darre Zereshk Porphyry- Skarn ores were selected as a case studies in Uramia- Dokhtar Magmatic Belt,. In this research, discovering this correlation procedure was performed by using surface and subsurface data (i.e. drilling data as geotechnical and Cu-percentage data) from Aliabad and Darre Zereshk mine districts. The results show that RQD criteria extracted from fault zones have a good correlation with surface faults which are identified by field investigations and Remote Sensing techniques. Also, the copper enriched was observed along fault zones and therefore, the relationship between porphyry copper deposits and fault zones is approved.
